Skill: Extend number patterns by 10

Explanation and Free Practice Resources

A number pattern that extends by 10 has a constant increase of ten from one term to the next; the learner continues sequences within 0–100 by identifying the next number as ten greater, including patterns that cross a decade. Place-value and number-line representations show that the ones digit stays the same while the tens digit increases by one, laying foundations for efficient addition and understanding the base-ten system without extending to larger numbers or formal algebraic rules.

Detailed Explanation: Extend number patterns by 10

To extend a pattern by 1010, add ten to each number.

Look at this pattern:

29, 39, 49, __, 6929,\ 39,\ 49,\ \_\_,\ 69
  1. Compare the first two numbers:

29→3929 \to 39

The number increased by 1010.

  1. Add 1010 to 4949:

49+10=5949+10=59
  1. Check the place values. The ones digit stays 99, while the tens digit increases by 11:

    • 4949 has 44 tens and 99 ones.
    • 5959 has 55 tens and 99 ones.

So, the missing number is:

59\boxed{59}
